Via the Irish Times:
Polling stations across the country have opened for the referendums on same-sex marriage and reducing the age of presidential candidates. Just over 3.2 million people are entitled to vote today. Polling stations opened their doors at 7am and will remain open until 10pm today. All Irish citizens aged 18 or over are entitled to vote, but only if their names are on the electoral register. There were 3.14 million names on the register when the date for the referendums was fixed, but 66,000 voters applied to have their names on the supplementary register before the deadline of May 5th. Voters will be given two ballot papers: a white ballot paper for the marriage referendum and a green ballot paper for the age of presidential candidates referendum. In the marriage referendum people may vote Yes or No to the proposal to include a new clause about marriage in the Constitution.
